1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Lakes on the Mongolian Plateau (MP) are vital freshwater and ecological resources, yet comprehensive long-term records of their area and water quality dynamics have been lacking. To fill this gap, we developed the Mongolian Plateau Lake Dataset (MPLD)-the first open-access, spatially explicit dataset providing annual records (1990-2020) of lake extent and three water quality indicators (Secchi Disk Depth, Total Suspended Matter, and Forel-Ule Index) for 1,161 lakes ( > 1 km², including artificial reservoirs). Built from over 56,000 Landsat scenes processed via Google Earth Engine, the dataset reveals a pattern of initial lake shrinkage followed by partial recovery, with total lake area reaching 19,592.78 km² by 2020. By that year, 71.83% of lakes were classified as eutrophic (FUI ≥ 10).The data show strong spatiotemporal heterogeneity: western and northern lakes expanded and cleared, while eastern and central Inner Mongolia saw contraction and water quality decline. The MPLD provides critical support for water resource management across the MP and serves as a valuable reference for global studies on climate change and dryland dynamics.
